What is measles?

Measles is a highly contagious virus that can cause serious complications.

Measles is rare in Australia because vaccination is effective in preventing the disease. However, people returning from overseas can still bring back the virus as measles is still common in many parts of the world Australians visit for holidays or to see family and friends.

What are the symptoms of measles?

The first symptoms of measles are:

  • fever
  • tiredness
  • cough
  • runny nose
  • sore red eyes
  • feeling unwell.

A few days later, a rash appears. The rash starts on the face, spreads down to the body and lasts for 4-7 days. The rash is not itchy. Some people, particularly young children, may also have diarrhoea.

Measles symptoms usually start 10 days after being exposed to the virus. They can appear as early as 7 days or as late as 18 days. The rash usually starts around 14 days after exposure.

Measles is a serious disease. Up to a third of people with measles have complications and many need to go to hospital. Complications can include ear infections, diarrhoea, and pneumonia. About one in every 1000 people with measles develops encephalitis (swelling of the brain).

How does measles spread?

Measles is very easy to catch. You can get it by breathing in the virus after someone with measles coughs or sneezes. Just being in the same room as someone with measles can result in infection.

People with measles can spread the virus from just before the symptoms start until four days after the rash appears.

Who is at risk of measles?

People are at risk of measles if they have contact with someone with measles infection and:

  • they have never had measles infection or
  • they have not had two doses of a measles-containing vaccine or
  • they have a weak immune system (for example, people having chemotherapy or radiotherapy for cancer, or people who take strong steroid medications). This is true even if they have been fully immunised or have had measles in the past.

How is measles prevented?

The best protection against measles is to get vaccinated. Two doses of measles vaccine, given at least four weeks apart, provide long-term protection for 99% of people.

Who should get vaccinated?

Anyone aged 12 months or older who was born after 1966 should be vaccinated.

  • Children normally get two free doses of the measles vaccine through the National Immunisation Program. They are usually given at 12 months and 18 months of age.
  • People born after 1966 who don’t know if they’ve had two measles vaccines, or know they haven’t, can get a free Catch-up vaccine.

Doctors may recommend that babies aged 6 to 12 months get vaccinated before overseas travel or during an outbreak.

Frequently asked questions about measles vaccination

How is measles diagnosed?

Measles is suspected when a person feels unwell, has a cough, runny nose or sore eyes and a fever, followed by a rash.

If a doctor thinks it might be measles, they will take a swab from the nose and throat, or a urine sample to confirm. A blood test may also be done.

Confirming measles is important, so public health can follow up with people who may be at risk of getting sick.

How is measles treated?

There is no specific treatment for measles. People who have measles should rest, drink plenty of fluids, and take paracetamol to help reduce the fever.

Some people may become very sick and need to go to hospital for care.

What to do if exposed to measles

Look out for symptoms for 18 days after you were last in contact with the person who had measles.

During this time, try not to have contact with anyone who is at higher risk of measles, such as babies who are too young to be vaccinated.

If you start to get symptoms of measles:

  • do not go to public places such as work, school, child care or shops
  • do not use public transport
  • see a doctor, preferably a GP, as soon as you can
    • call before you arrive and tell staff about your symptoms, so they can limit your contact with other people
    • if you were given a Measles contact assessment form, take it with you
  • call your local Public Health Unit (1300 066 055).

How to reduce the spread of measles

People with symptoms of measles should call ahead before going to an emergency department or GP. Tell staff about your symptoms and any recent travel, contact with a known measles case or exposure location. When you arrive, ask staff for a mask and wear it to help protect others. They can also isolate you to reduce the risk of spreading measles.

People with measles should stay at home until they are no longer infectious. That is four days after the rash starts. Staying home helps stop the virus from spreading to other people.
